5.23.5. Installing Packages in the DUT Without the Package Manager

When a test requires a package built by BitBake, it is possible to install that package. Installing the package does not require a package manager be installed in the device under test (DUT). It does, however, require an SSH connection and the target must be using the sshcontrol class.

Note

This method uses scp to copy files from the host to the target, which causes permissions and special attributes to be lost.

A JSON file is used to define the packages needed by a test. This file must be in the same path as the file used to define the tests. Furthermore, the filename must map directly to the test module name with a .json extension.

The JSON file must include an object with the test name as keys of an object or an array. This object (or array of objects) uses the following data:

Following is an example JSON file that handles test "foo" installing package "bar" and test "foobar" installing packages "foo" and "bar". Once the test is complete, the packages are removed from the DUT.

     {
         "foo": {
             "pkg": "bar"
         },
         "foobar": [
             {
                 "pkg": "foo",
                 "rm": true
             },
             {
                 "pkg": "bar",
                 "rm": true
             }
         ]
     }
